28.6 Numeric arrays [numarray]

28.6.4 Class slice [class.slice] Overview [class.slice.overview]

namespace std { class slice { public: slice(); slice(size_t, size_t, size_t); slice(const slice&); size_t start() const; size_t size() const; size_t stride() const; friend bool operator==(const slice& x, const slice& y); }; }
The slice class represents a BLAS-like slice from an array.
Such a slice is specified by a starting index, a length, and a stride.233
BLAS stands for Basic Linear Algebra Subprograms.
C++ programs can instantiate this class.
See, for example, Dongarra, Du Croz, Duff, and Hammerling: A set of Level 3 Basic Linear Algebra Subprograms; Technical Report MCS-P1-0888, Argonne National Laboratory (USA), Mathematics and Computer Science Division, August, 1988.
